Here’s a good laugh line if you find yourself in a policy meeting about how to reduce gasoline use: suggest increasing the gasoline tax. During my time in the White House, I attended several meetings on this topic, and inevitably someone (sometimes me) would offer that simple idea. Everyone would then chuckle at its political insanity, and the conversation would turn to Washington’s policy of choice, increasing fuel efficiency standards for autos and cars.

Those standards certainly can reduce future gasoline usage. But they are an incredibly inefficient way to do so. For some new evidence of just how inefficient, let’s turn the microphone over to the aptly-named Valerie Karplus, an MIT researcher, writing in the New York Times:

Politicians of both parties understandably fear that raising the gas tax would enrage voters. It certainly wouldn’t make lives easier for struggling families. But the gasoline tax is a tool of energy and transportation policy, not social policy, like the minimum wage.

Instead of penalizing gasoline use, however, the Obama administration chose a familiar and politically easier path: raising fuel-efficiency standards for cars and light trucks. The White House said last year that the gas savings would be comparable to lowering the price of gasoline by $1 a gallon by 2025. But it will have no effect on the 230 million passenger vehicles now on the road.

Greater efficiency packs less of a psychological punch because consumers pay more only when they buy a new car. In contrast, motorists are reminded regularly of the price at the pump. But the new fuel-efficiency standards are far less efficient than raising gasoline prices.

In a paper published online this week in the journal Energy Economics, I and other scientists at the Massachusetts Institute of Technology estimate that the new standards will cost the economy on the whole — for the same reduction in gas use — at least six times more than a federal gas tax of roughly 45 cents per dollar of gasoline. That is because a gas tax provides immediate, direct incentives for drivers to reduce gasoline use, while the efficiency standards must squeeze the reduction out of new vehicles only. The new standards also encourage more driving, not less. (Emphasis added.)

A gas tax wouldn’t be a win-win all around, of course. People would pay more in taxes immediately. So you might well want to pair the tax with other policies (e.g., offsetting tax reductions) to ameliorate that hit. (The same concern applies to carbon taxes.)
